IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 26,152], dated November15, 1859.

To all whom it may concern:

Be it known that I, ISAAC N. PYLE, ot' Decatur, in the county of Adamsand State of Indiana, have invented a new, useful, and ImprovedCultivator; and I do hereby declare that the following is a full, clear,and exactdescription thereot', reference being bad to the accompanyingdrawings, and to the letters of reference marked thereon, in which-Figure 1 represents a perspective view of the cultivator, showing theconstruction of the same. Fig.2 is a plan view with the handles of thecultivator-removed. Theparts are shown by this figure in two positions.

My invention consists in an improved mode of adjusting the wings of thecultivator and also the central beam, so that the wings may be spreadout or contracted by a simple arrangement, hereinafter described.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe its construction and operation.

A A represent the two wings, which are made of round iron rods andpivoted by strong pins to a between two lateral plates, 1) b. The rearportions of these rods A A are curved, as represented by Fig. 1, and theends flattened, and to these ends are bolted the shovels B B, the properinclination being given to the shovels by the curvature of the rods.

0 is a central rod or beam, which has its rear end curved and providedwith a shovel, B, making a triple-shovel cultivator. This center beam,0, is capable of a longitudinal adjustment by loosening the thumb-screwc, and to this beam is attached the team for drawing the machine throughthe ground.

E E- are the handles, which are secured to sockets F F, and said socketsare provided with loops or rings G G on their ends, which encompass thewings A A and move back and forth upon them in adjusting the cultivator.These handles are supported by vertical standards J J, which may be madeof any suitable stiff metal. These rods forming the standards are woundaround the wings, as clearly shown by Fig. 1, forming rings K, which areconnected to the cross-brace L by rods M M. The crossbrace L is attachedto the rods forming the wiugsAA,andalsoto thecenter beam,0,inthe samemanner as the standards are connected to the wings-viz., by rings whichcan be moved upon the rods when it is desired to adjust the parts.

N is a lateral brace-rod for the handles E E.

With this arrangement the adjusting of the wings can be effected bysimply moving the handles longitudinally, the brace L, rods M M, andstandards all being moved simultaneously.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

The arrangement and combination of the curved pivoted wing-rods A A,curved adjustable central rod, 0, looped sockets F, vertical movablestandards J ,rodsM, braces L, and handles E, as and for the purposeherein shown and described.
